TYPE-WRITING MACHINE.

Patented Dec. 26, 1911.

To all whom'it may concern:

Be it known that I, CHARLES E. SMITH, a citizen of the United States,and resident of the borough of Brooklymcity of New York, in the countyof Kings and State of New York, have invented certain new and usefulImprovements in Type-Writing Machines, of which the following is aspecification.

My invention relates to typewriting machines and more particularly tomeans whereby tabulating operations may be automatically effected as thewriting proceeds and. without the exercise of any care or judgment onthe part of the operator and without the necessity of actuatingtabulating keys.

A further object of my invention is to provide in a construction of thecharacter specified above,hand controlled means operable at will to moveone of two cooperative disengaging devices into or out of cooperativerelation with the other of said disengaging devices and for maintainingit in either of such positions, thus rendering the automaticallyoperating tabulating means operative or inoperative, as may be desired.

-To the above and other ends which will hereinafter appear, my inventionconsists in the features of construction, arrangements of parts andcombinations of devices to be hereinafter described and particularlypointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicatecorresponding parts in the various views, Figure 1 is a fragmentaryvertical front to rear sectional view showing the upper portion of atypewriting machine embodying my invention. Fig. 2 is a fragmentary rearelevation with parts in section showing the devices of my invention andsome of the associated parts. Fig. 3 is a detail fragmentary perspectiveview of a part of the controlling means for rendering the tabulatingmechanism operative or inoperative. Fig. 4 is a detail perspective viewof one of the cooperative members by which a disengagement between thefeed rack and pinion is effected. Fig. 5 is a rear elevation of the samewith some of its associated parts. Fig.

6 is a fragmentary vertical front to rear sectional View showing theupper portion of a typewriting machine illustrating a modlfied form ofconstruction embodying my in-' vention. Fig. 7 is a rear elevation ofthe same with parts sectioned away. Fig. 8 is a fragmentary rearelevation showing some ner posts 1 and a top plate 2. Fixed oppositelygrooved guide rails 3 are secured in the usual manner to the top plateof the machine and anti-friction balls or rollers Tare received in thegrooves in said rails and are likewise received in oppositely groovedtracks 5 in the rear cross or guide bar 6 of the carriage. Forwardlyextending arms or end bars 7 project from the cross bar 6 and areprovided with bearings to receive a platen shaft 8 on which acylindrical platen 9 is mounted for rotative movement. Rearwardlyextending arms 10 are pivoted at 11 to the carriage and support at theirrear ends a feed rack 12 which meshes with a feed pinion 13 fixed to theforward end of a shaft 145 mounted to turn in a bearing bracket 15secured to the top plate of the machine. The rear end of the shaft 14:is operatively connected to an escapement wheel 16 by the usual pawl andratchet mechanism contained within a drum 17 and by which the feedpinion and escapement wheel are fixedly connected to turn together inone direction and by which the shaft 14' and pinion 13 may be turnedbackwardly. independently of the escapement wheel during the travel ofthe carriage from left to right. Feed dogs 18 are carried by a dogrocker 19 and cooperate with the escapement wheel to effect astep-by-step letter feed of the carriage in the usual manner during theactuation of the finger keys. The feed rack is preferably perforated at2O throughout'the length thereof, the distance between adjacentperforations corresponding to the spacing between'the teeth prises anengagmg arm or member 23 adapt ed to be received in one of the recesses21 and also comprises a parallel engaging arm .24 adapted to be receivedin the corresponding opening in the feed rack, in order to hold andmaintain the disengaging device I as a whole in the position to which itmay be adjusted along the feed rack. The arm 24 is extended rearwardlyto form a contact portion 25 which is looped on itself and constitutes afinger piece by which the disengaging device may be gripped by thefingers of the operator and withdrawn from its engaging apertures andrecesses and adjusted from one position to another along the feed rack.The construction is such that the disengaging devices 22 may be adjustedto any letter space position .in the travel of the carriage and may, ifdesired, be adjusted to adjacent apertures and re cesscs for purposeswhich will hereinafter more clearly appear. a

A cotiperative disengaging member is designated as a whole by thereference numeral 26 and is shown in detail in Fig. 4. This member hasoppositely disposed cam faces 27 and-27 and a dwell 28 at the upper edgethereof. The member 26 is slotted at 29 to straddle the bearing 15 forthe escapement shaft, said bearing being slotted on each side as at 29to receive the member 26 and guide it in its vertical movements. Thelower end of the member 26 is provided with outwardly extending arms 30apertured to receive headed screws 31 which are received at theirthreaded ends in tapped openings in a cross piece 32 provided centrallythereof with a forwardly extending pin 33. The member 26 is alsoreceived behind the head of a T-shaped lug 34 which projects from thelower fixed rail 3. The stem of this lug is received in the slot 29 andthe head of the lug overlaps the member 26 and it is thus guided by thelug 34 and the walls of the slots 29 in the bearing 15, as said member26 is moved vertically from the posit-ion shown in-Fig. 2 to thatrepresented in Fig. 5.

I have provided hand controlled means for effecting a vertical movementof the member 26 in order to move it into or out of coiiperativerelation with the disengaging devices 22. Thus, a bar or frame 35 isslotted at 36 to receive headed screws 37, the stems of said screwsbeingreceived in tapped openings in the lower fixedrail 3 of. the

machine. The right-hand end of this bar 35, as the parts appear in Fig.2, is pivoted at 38 to an upwardly extending crank arm 39 which projectsthrough a slot 40 in the top plate of the machine. The crank arm 39fixed to a horizontally disposed rock shaft 41 mounted to turn inopenings in brackets 42 fixed to and depending from the top plate of themachine. As will be seen in Fig. 1, this rock shaft extends from therear of the machine, where it carries the crank arm 39, to the frontwhere it is provided with a depending arm 43, preferably enlargedlaterally as indicated at 44 in Fig. 2. This enlargement is to provide asurface on which indicating means 45 and 46, such as In and Out may beinscribed. These indices are adapted to be brought into register with asight opening 47 in a front plate 48'of the machine; it being understoodthat the depending arm 43 is situated in the rear of said front plate. Asegmental slot 49 is provided in the front plate and through this slotprojects a finger piece 50 carried by the crank arm 43 and by which thecrank arm and the parts connected therewith may be controlled. It willbe understood that when the finger piece 50 is moved to one end of theslot, as represented in Fig. 2 for example, the word Out is exposed atthe sight opening 47 in the front plate to indicate that the mechanismis out of operation, whereas, when the finger piece is shifted to theother end of the slot 49 the indication In is brought into register withthe sight opening to ex-- pose it and. thus indicate that the tabulatingmechanism is in operation.

The pin 33 hereinbefore referred to is received in a cam slot 51 in adepending portion 52 of the bar 35; and a dwell 53 at each end of thecam slot cooperates with the pin 33 at the end of the movement of thebar in either direction so as to hold or maintain the member 26 ineither the uppermost or lowermost-position to which it may be adjustedby an actuation of the finger piece 50.

The members 26 and 32 are connected together in the manner shown byscrews 31 to ficilitate assembling the parts in the ma- 0 me.

When the parts are in the position shown.

in Fig. 2 the mechanism is thrown out of operation, that is to say, thebar 35 will be moved to the right, as the parts appear in said figure,and the cam 51 will effect a lowering of the member 26 to a point whereit is out of cotiperative relation with the disengaging devices 22carried by the feed rack. When, however, the finger piece 50 is shiftedto the right, as the parts appear in Fig. 2, the bar 35 will be moved tothe left, thus camming the member 26 upwardly so as to bring the upperend thereof into the path of the various disengaging devices 22 carriedby the feed rack. I

In the operation of the devicethe operator will first set thedisengaging devices 22 at the positions along the feed rack where it isintended to disengage the feed rack from 5 its feed pinion and afford afree travel of" the carriage or a tabulating movement of the carriage.After the members 22 have been set in accordance with the character of.the work to be produced, the operatorwill loproceed with the Writing andduring the 1 feed movement of the carriage in the i tion of the arrow inFig. 2, and under the power applied thereto by the spring drum= 5-1, thefirst of the disengaging devices 22 will be brought into .coiiperationwith the vice 22 over the dwell 28 on the member 26.

As soon as the engaged device 22 passes the 1 25 dwell it will ride downon the opposite cam 1 face 27 a and a reengagement of the rack with itsfeed pinion will be effected. The weight 1 of the rack itself mayberelied upon to effect I this rengagement, or the springs usually 30employed may be provided to assist the reengagement between the rack andthe pin-} ion. In thepresent instance I have shown the parts soproportioned that the extent of tabulating movement of the carriageeffected by the coiiperation of one of the devices-1 22 with the member26 corresponds to two letter space movements of the carriage. The 1extent of this movement, however, may bei varied according to the workto be produced. I

If it is desired to provide a free skipping movement of the carriage forthe extent of three instead of two spaces, then two of the 1 disengagingdevices 22 may be adjusted one next to the other to effect the desiredextent v of skipping movement of the carriage. The

character of the work in some instances may be such that it may be founddesirable to provide greater extents of engaging surface on the members22 and 26. The extent of such surfaces may be varied as desired.

During the return movement of the carriage the devices 22 will bebrought successively into engagement with the cam face 27 to cause therack to be lifted and thus enable the devices 22to clear the member26during the return of the carriage.

In order to throw the automatically operating tabulating mechanism outof operation it is merely necessary to shift the finger 80 piece 50 tothe position shown in Fig. 2, thus moving the bar 35 to the right, asthe parts are shown in this figure, to eflect a downward movement of themember 26 by the connection of the latter with the bar 35 through theintermediate cam slot 51 and the pin 33. As long as the finger piece ismaintained in the position shown the tabulating mechanism is renderedinoperative.

In Figs. 6, 7 and 8, I have shown a modified form of constructionembodying my invention inwhich practically a reversal of theconstruction shown in the preceding figures is represented. In Figs. 6,7 and 8 a bar 55 extends longitudinally of the carriage adjacent to thefeed rack 1.2 and is provided at its ends with upwardly directed arms 56secured to the upper fixed guide rail 3 by screws 57. The fixed bar 55is apertured and recessed in substantially the same manner as the feedrack was in the construction shown in the preceding figures. Thus thebar 55 has a series of apertures 58 extending longitudinally thereof atletter space distances apart and the upper edge of the bar iscorrespondingly recessed at 59. Disengaging devices, each designated asawhole by the reference numeral 60, are adapted to be engaged with thefixed bar 55 in the same general manner as the disengag ing devices 22are engaged with and disengaged from the feed rack in the previouslydescribed construction. Thus, each of the disengaging devices 60 isprovided with an arm 61 adapted to be received in an opening 58 and islikewise provided with an enlarged head 62 adapted to be received in thecorresponding recess 59 in the upper end of the fixed bar. A disengagingor cam member 63 in the nature of an angular bracket is secured by ascrew 64 to the feed rack, as represented in Figs. 6 and 8. Thisdisengaging device is provided with oppositely inclined cam faces 65 and66 which co6perate with the enlarged heads 62 on the disengaging devices60 to lift the feed rack and thus disengage it from its cotiperativefeed pinion. A dwell 67 is provided on the device 63 between the camfaces 65 and 66 for co6peration with the heads of the disengaging devices 60. It will be understood therefore that in the step-by-stepmovement of the carriage the overhanging cam member 63 on the feed rackwill be brought into cooperation withthe disengaging devices 60 whichare held against movement on the fixed bar 55 to lift the feed rack anddisen gage it from the feed pinion and thus afford,

Without modifying the structural features of such machines. Thus, thebracket provided with the cam 6667 may be attached to the feed rack andthe fixed bar 55 carrying the disengaging devices 60 may be attached tothe upper fixed guide rail by the screws 57 and no changes in thestructural features of the machine are necessary in order to apply thedevices to machines now on the market.

In the modified form of the construction shown in Figs. 6, 7 and 8 Ihave employed corresponding numerals to those employed in the previouslydescribed construction where the parts are the same.

It will be observed that in each of the constructions shown the feedrack constitutes one of two feed devices, the other or cooperative feeddevice is the feed pinion; that in each case there is a disengagingdevice 22 or 63 carried by the feed rack; that there is a seconddisengaging device 26 or 60 separated from the cooperative feed deviceand cooperative with said first mentioned disengaging device toautomatically disengage the feed rack from its cooperative feed deviceat a given point in the travel of the carriage in the direction of itsfeed and that in each of the constructions shown there is a feed rackhaving a disengaging device 22 or 63 having an engaging projectionarranged at one side of the feed rack and above the teeth thereon.

Various changes may be made without departing from the spirit and scopeof my invention.
